To all whom, t may concern.-

Be it known that I, FREEBORN F. RAYMOND,

2d, of Newton, in the county of Middlesex and State of Massachusetts, a citizen of the United States, have invented anew and useful Ilmprovement in Heel Forming and Compress- 1 ing Machines, of which the following'is a full,

u machine in front elevation.

clear, and exact description, reference being had to ther accompanying drawings, forming a part of this specitication,in explaining its nature. f

The invention relates to a machine for shaping the sides and heel-seat of heel-blanks, emf ploying an open-mouthed stationary die, a reciprocatingheel-seat former, and an automatic heelblank-feedingdevice.

It also relates to various details of organization and construction, vall'of which will be hereinafter described. i

yIn the drawings, Figure lis a view of the Fig. 2 is a vertical section upon the dotted linesx x offFig. 1. Fig. 3 is a horizontal section upon the lines y y of Fig. 2, and in plan ,of the parts below it. Fig. 4 is a view of kthe heel-blank carrier en larged. Fig. 5 is adetail view.

Referring to the drawings, A represents the bed of the machine; a, the'dieblock. It is preferably square in shape, and fits the recess a in the bed, being, locked therein bya pin, a2. The die-block has the die a3, the Llower section and sides 'of whichy have the shape which it is desired to "give the sides of the Yheel-blank, and from the mouth of the die there are outwardly 'sloping or Haring sides a4. The bottom of the die is formed by the imperforate plate a5, formed on the end of along rod, a6, which extends down through a holein the die-block and isv moved upward by a spring, al.

B is a box or receptacle for holding the heelblanks to be compressed. This box is suitably supported, and has the opening or mouth b,

f through which the heel-blanksare fed in succession over the die. ATheheel-blank-feeding device comprises ythe slide-plate b', having .lever by the link 118.

C'is the cross-head. It preferably is. recip- The plate is operated by means of a lever,"b5,

rocated inv the manner described in the Hen'-Av dersonipateut, No. 316,894, and it carries either a single arm, c, supporting the heelseat.

'i There .is formed i'n the die-'block a hole,d,

whichA receives the heel-blank holder or strip-l per D. This stripper or holder comprisesa rod, which is movable upwardby the spring d and downward by the block c2, supporting l i the heel-seat former. It 'also has a latch, dz, which is adapted lto be engaged by the catch d3 automatically when it is moved down, and to be held down until the catch is moved to permit it4 to be lifted by its spring by the con.- tact of the block d* upon theslide-plate b with a part of the latch, the block inoving-thelatch end inopposition to the spring d5 sufficiently to disengage it from the catch. ofthe blank-holder doesy not take place,hovv. ever,until the heel-blank has been moved into' the position represented in Fig. 2-thatis,over

thearing mouth of the die.

This .release l The operationof the device is as follows: V

The cross-head C and the heelseat former c; ,y a being at their highest position, the diaphragm,

a5 is also in its highest position and is on a level'withthe upper surface ofthe dieblock,

andthe heel-blankis ina position over the mouth of the die resting upon the upper surface of the diaphragm, and the stripper'or heel-blank holder D, having. been released, is

in a position to hold the heel-blank againstthe backward. movement of the plate b'L, Upon the sarting of themaohine the platebis moved rapidly backward', leaving the heel- -blank upon the diaphragm and engagingthe` lowermostheel-blankinthe stack D. Theheelseat former cimrnediately descends, and,strik`4 ingthe top of the heel-blank,forces it andthe i l Vdiaphragm down into the die-cavity and so-v lidifies the blank therein and forms thelheelfA seat. Upon the lifting of the former thefdia-y phragm follows it until its upper surface rco reaches substantially the level of the die-block, o

when its movement is stopped,and the slideplate b', with a heel-blank, is then rapidly moved out from the stack and knocks olf the heel from the top of the diaphragm while the unformed heel is broughtinto position, and at the same instant the holder or stripper D is released and moves upward to hold the heelblank upon the diaphragm during the backward movement of the plate b and the heelholders b3.

It'Wll be understood that the stripper or holder D has previously been moved downward by the arm c2 and engagedby the latch d3.

Having thus fully described myinvention, I claim and desire to secure by Letters Patent of the United States- 1. The combination, in a heel forming and compressing machine, of the bed A, the stationary die-block a, the vertically-movable diaphragm a, a reciprocating head, C, the

heel-seatforming block c', carried thereby, with a heel-blank carrier, substantially as specified, for transferring a heel-blank from one position to a position over the opening to the die and diaphragm, substantially as described.

2. The combination, in a heel-blank forming and compressing machine, of the bed A, the die a, the vertically-movable diaphragm a5, the reciprocating head C, the heelseat former c', carried thereby, the blank-carrier, and a blank stripper or holder for holding the blank upon the diaphragm during the reverse movement ofthe carrier, substantially as described.

3. The combination, in a heel-blank forming and shaping machine, of the bed A, die a, vertically'-movable diaphragm ai", vertically-movable head C, the seat-forming block c', carried thereby, a hcel-blank-carrying device, the heelblank holder D, adapted to be moved downward by the block c?, carried by the heel-seat former, and to be moved upward by a spring, d', and a latch forlocking the holder or stripper depressed, and a projection carried by the heel-blank-feeding plate for moving said latch to release the holder after the movement of a heel-blank into position upon the diaphragm, substantially as described.

4. The combination, in a heel-blank forming and shaping machine, of the bed A, the dieblock a, the vertically-movable diaphragm a5,

the reciprocating head C, the heel-seat former c', with the stack B, for holding heel-blanks, having the mouth-b, slide-plate b', having the long arms b2, and laterally-movable heeLbIankgrasping devices b3, carried by said arms b", substantially as described.

5. The combination of the stack B, for holding heel-blanks, with the slide-plate b', having the long opening formed by the arms b2, which are disconnected at their front ends, and the heel-blank-grasping jaws b3, attached to or carried by said arms and laterally movable in relation to each other, as and for the purposes described.

6. The combination, in a heel-blank forming and shaping machine, of the head A, die a, the diaphragm a5, its operating-spring a?, the head C, the heel-seat former c', car-ried thereby, the slide-plate b', carrying the heel-grasping devices, the stripper or holder D, its operatingspring cl, a locking device for locking the stripper when moved down, the crank-shaft, and a cam, b, thereon, connected with the slide-plate b', all as described.

7. The combination of the die A, the vertically-movable diaphragm a5, and the reciprocating plate or heelb1ank holder for knocking or removing the formed heel-blank from the upper surface of the diaphragm, as and for the purposes specified.
